CLOSURE Filed Feb. 27, 1928 Patented July 12, 1932 UNITED STATES PATENT OFFICE JAMES B. REID, OF CLEVELAND, OHIO, ASSIGNOB, BY MESNE ASSIGNMENTS, 1'0 EATON MANUFACTURING COMPANY, OF CLEVELAND, OHIO, A. CORPORATION Q! CLOSURE Application filed lebruary 21, 1028. Serial no. 257,388.

This invention relates to closures for re- I ceptacles and particularly to that type of motor vehicles.

In the automobile industry, manufacturers and other designers spend much time, money and 'efiort upon the articular shape and design of the ca s use .on the radiators, the dust pan at the ront for the crank, the gasoline tank and in other places where caps or closures are to be used. The design and shape and construction of these arts change quite frequently, usually with t e change of a model each year. 'It is not necessary to set down the reasons for these changes, but the fact remains that such changes are made from time to time. For some time these closures for the main art have been round in configuration, there y lending themselves very nicely to closure structures where the cap or closure itself is applied and removed by rotation, the articular securing means for the cap being either threads or bayonet cam arrangements.

Recently there has been a desire, among those interested, in this particular art, to have shapes which are oval or something other than round and, in most instances, it is necessary when employing such shapes to have them seat down over a bead upon the ad acent part. For exam le, the radiator cap must tit down over a ad on the combing or shell of the radiator. This arrangement obviously prevents rotation of the cap for application and removal.

In view of the foregoing, the present invention relates to a closure structure for use in connection with radiators, dust pans and the main cap portion seals the filler neckor' other part to which the cap is applied. l The specific arrangement is one where the seat 7 is provide main or internal cap structure is connected to the filler neck, for example, by the now well known bayonet-like arrangement, while the ornamental cap structure is so mounted upon this main cap structure that it may be moved relative thereto or raised so that in removal the entire cap structure, as a whole, may be rotated for removal and application of the main cap structure to the filler neck or other part. v z

Other features of inventipn will be brought out in the following description, drawing and claims.

In the drawing, Fig. 1 represents a top plan view of the closure; Fig. 2 shows it shifted to position for removal; Fig. 3 is a section upon the line 3-3, Fi .1; Fig. 4 is a section on the line 4-4, F1g. 3; Fig. 5 is a section upon the line 5-5, F1g. 3; Fig. 6 is a section upon the line 6-6, Fig. 3; Fig. 7 is a top plan view of the neck; and Fig. 8 is a section on the line 88, Fig. 5.

' In the drawing, 1 represents the dust an or radiator shell, which is provided wit a suitable neck 2 provided with an inner flange 3 interrupted at 4 and having inwardly extending cams 5 for cooperation with the cap lock to be described. Where necessary, the

flange 3 forms a seat for a gasket 6. The

arrangement just described is substantially that prevailing at the filler o ening of the radiator, the crank dust guar opening and the'gasoline tank and it is in conjunction with this and like mechanism that the present invention has been devised.

Cooperating with this neck structure is a main lnner cap structure including a seat flange 7 provided with a head 8 for engagement with the gasket 6 when used. This with an integral inwardly extending pilot boss 9 which is hollow and receivesa locking member 10 having oppositely extending spring fingers 11 projecting through opposed slots or openings 12 in the sides of the boss 9 where they may engage with the came 5 in the formation of the bayonet lock with the neck. So far,'the construction is similhr to that which is already present in the prior art and it is referred to here for the purpose of clarity and for the purpose of the filler neck the seat or flange 7 is beaded .over, as at 13, around the edge of a disk or circular plate 14 which forms a closure for the opening in the boss 9 and therefore completes the closure of the main inner cap or closure structure. If necessary, this plate may be provided with a vent opening 15 where the device is used on a gasoline tank. Engaging in the bead 13 is a ring 16, preferably of spring stock and provided with four outwardly extending flange skirt portions 17 within the bead 13 and four upstanding lugs or arms 18 each provided with an inwardly extending rounded projection 19 for apurpose to be described. The ends of the upstanding arms or lugs 18 are provided with outwardly bent foot portions 20 adapted to engage the inner face of the ornamental cap portion or skirt 21. This ornamental cap skirt portion 21 extends down and around a bead 22 formedon the shell or pan 1, when the skirt portion 21 is in engagement with the foot portions 20. The central part of this skirt or ornamental cap is provided with a suitable knob or other ornamentation 23 which may be grasped by the operator.

The arms or lugs 18 extend up through suitable slots 24 in an insert plate 25 provided with a flange 26 spotted or otherwise secured to the inner face of the skirt portion 21. With the cap in place, as in Fig. 3,- the operator grasps the knob 23 and presses upon it laterally, preferably at the front. This causes the ornamental cap structure, as a whole, to move up upon the lugs or arms 18 which spring back and permit the plate at the slots 24 to engage above the projections 19. The ornamental structure is then pulled up in the opposite direction when the low side will move above the projection 19. In this way the ornamental cap structure is moved up relative to the main cap structure and to a position where the lower edge of its skirt 21 is above the bead 22 on the radiator shell or pan. The entire cap structure may then be rotated to release the lock, when removal is possible. The foregoing arrangement is especially useful where the ornamental cap structure is other than round in configuration andwhere it fits down over a bead or other formation which prevents rotation when in final assembled position.

In application, the ornamental cap structure is in the upper position and the main cap structure is applied to the neck locked in place and the ornamental cap structure forced down to final position.

What I claim is:

1. A closure for a receptacle neck extending through a surrounding member, com ris ingian inner member provided with 100 ing means adaptedfor releasable assembly with said neck by rotation relative'thereto, an

outer member having a transversely extending wall portion therein provided with a plu-. rality of openings, and a plurality of arms connecting said inner and outer members whereby said inner member magebe rotated by said outer member, said arms ing movable in said openings to permit axial movement of said outer member relative tosaid inner member whereby said outer member may be moved into and out of engagement with said V surrounding member.

2. A closure for a receptacle neck extending through a surrounding member, com rising an inner member provided with loc ing means adapted for releasable assembly with said neck by rotation relative thereto, an outer member having a transversely extending wall portion therein rovided with a plurality of openings, a p urality of upstanding arms connecting said inner and outer members wherebysaid inner member may be rotated b said'outer member, said arms being movable in said openings to permit axial movement of said outer member relative to said inner member whereby said outer member may be moved into and out of engagement with said surrounding member; and latch means on said arms restricting their movement in said openings.

3. A closure for a receptacle neck extending through a surrounding member, comprising an Inner member provided with locking means adapted for releasable assembly with said neck by rotation relative thereto, an outer member having a transversely extending wall portion therein provided with a plurality of openings, a plurality of resilient arms connecting said inner and outer members whereby said inner member may be rotated by said outer member, said resilient arms being movable in said openings to ermit axial movement of said outer mem er relative to said inner member whereby said outer member may be moved into and out of enga ement with said surrounding member, an latch means on said arms intermediate their ends for restricting their movement in said openings. In testimony whereof I hereby aflix my signature.
